2 sample pages behavior marred by onhover and oddly to me a simple div w table

i have these 2 pages

www.philipdusel.com/moon.html
and
www.philipdusel.com/ass.html

ideally my page will look something like moon.html w the menu at top…the prob is that the navigational arrows do not work and it is the header div preventing their functioning

the page ass.html has working navigational arrows but it is using the greyscale images to change the big image, how do i put the img id(what java is using to change images) on the colored version of image

id love some help…i have a headache

thanks:eye:

It looks to be a CSS problem.

Check the height that has been set for of your header menu.

that worked to get the arrows moving through the images but the javascript is calling on the img id of a grey scale version of the image that i want shown. perhaps there is a more concise way of doing this?

thanks for the help
